Multi :可以垂直水平运动的电梯

An Elevator That Actually Goes Sideways

2015年 我去了谢菲尔德
In June 2015, I went to Sheffield,
而且我看到了一个链斗式升降电梯
and I saw a paternoster lift,
一个废弃的由循环链组成的电梯设计
an obsolete design of elevator with a looping chain of open cabs.
2016年6月 我到意大利的热那亚旅行
In June 2016, I travelled to Genoa in Italy,
而我再一次看到了一个向侧面运动的电梯
and I saw an elevator that also moved sideways.
此外 剧透一下 那其实是骗你的
Except, spoiler, it’s a bit of a cheat,
实际上 它内部是一个水平运动的车
it’s actually a little horizontal car that moves inside
较大电梯运输重物
a bigger elevator that does the heavy lifting.
而此时此刻 即2017年6月
And now, it is June 2017.
蒂森克虏伯电梯测试塔上
And I’m in Germany, at the brand-newThyssenkrupp Elevator Test Tower,
他们带我给我展示Multi:
and they have flown me out hereto show off Multi:
他们的目前 最大的 工作中的电梯
their actual, full-size, working elevator
它是真真正正的向侧面运动
that moves sideways without cheating.
对我们来说 有一座塔用来测试
For us, it was very important to
我们的新技术是十分重要的
have a tower to test the new technology.
我们不想在消费者那里测试它
We don’t want to test itat the customers’ site.
这塔有246米高 这意味着它有1700步
The tower is 246m high,and this means 1,700 steps.
我知道得如此精确是因为我有一次走上去过
I know that exactly, because I walked up once!
这座塔完全是为了电梯轴而建立的
This is a building made almost entirely ofelevator shafts.
其中有一些是用来测试一般的电梯
Some of them test regular lifts,
但有一些是预备给新的系统
but some of them are reserved for this new system.
拥有持续旋转飘动的车子的原则
The principle of havinga continuous rotating flow of cars
是我们这一领域最好的发明之一
was one of the best inventionsin our industry ever.
而为了实现这一发明
And to achieve this,
我们需要把客舱从这一轴转换到另一个轴
we have to exchange cabins from one shaft to another.
为了完成这一转换 我们需要转换器
And to have this exchange, we need an exchanger,
就是我后面的这个
which you see just behind me.
这个转换器可以让我们实现水平运动
And this exchanger allows usto go into horizontal movement.
这个转换器可以安装在轴的任何一个部位
The exchanger can be placed at every pointin the shaft
因此它能让我们实现各种配置
so it allows us to do all kinds of configurations.
垂直地下来 然后做水平运动
Coming down vertically, and then going intothe horizontal movement.
电梯的问题之一便是这些很高的建筑
One of the problems with elevatorsin really tall buildings
需要很长的缆绳
is that you need a cable so long
但长绳有无法支撑自己的重量
that it can’t support its own weight,
更不必说以后连到上面的驾驶室
let alone the weight of the cab that’s then connected to it.
解决方法有点不同
The solution here is a bit different,
我们不用缆绳
and it doesn’t use cables at all.
我们换用线装感应电动机
It uses linear induction motors.
线装推动也是一种带着永久磁铁的同步发动机
Linear drive – it’s also a synchronous motorwith permanent magnets.
你可以把它理解为循环发动机
And you maybe know it from a rotating motor.
如果我们利用这个发动机
If we just take this motor
并把它的一侧镶嵌进去
and cut it on one side
然后再把它放到桌面上
and just lay it on a table flat,
这样 你就有了一个线装发动机
then you already have a linear drive.
这也是我们所拥有的 既可以垂直运动 又可以水平运动
And this is what we have,vertical and also horizontal.
在普通电梯中 它被称为牵引电梯
In a regular elevator,it’s called a traction elevator,
我们用电缆支撑驾驶室
you’ve got cables holding the cab,
其中一个便可以支持比自身设计重的物体
any one of which can holdmore than the design weight.
而且 我们还有紧急刹车 在电梯运动太快时
Also, you’ve got emergency brakeswhich will pop out
会弹出来 通过摩擦力减缓速度
and slow the car down with friction if it’s moving too fast.
而即使是最糟糕的情况下 如果紧急刹车失灵了
And, absolute worst case, even if all thatsomehow fails,
我们还有一个缓冲器
you have a buffer
它的底部可以把自由落体
at the bottom that should reduce a freefall drop
从“致命”降到“严重受伤”
from”fatal” to just”severe injuries”(!)
电梯是十分安全的 因为他们的运作井然有序
Elevators are incredibly safe because they’reincredibly well-regulated.
因此 在被允许承载人们之前
So before this is allowed to carry humans,
这一系统至少是“故障安全”的
this system needs to be at least as failsafe.
这一安全并不仅仅是
The safety is not just in the ropes
常见的电梯绳索的安全
of a conventional elevator
还有刹车系统
but in the brake system.
在一般的电梯中 刹车装在
In conventional elevators, you have the brake
轴顶端的机房里的
on the machine on top of the shaft
机器上
in the machine room
而现在 我们把刹车直接安装在车身
now we have the brake directly on the cars.
这一新的组件 即可以让我们
This new component, the exchanger,
从垂直运动转换到水平运动的转换器
where we go from vertical into horizontal movement,
也需要接受操控员的检查
also needs to be checked by our safety controller.
(操作员需要检查)转换器在哪个位置?
What is the position of the exchanger?
有没有锁好?
Is it locked?
是否安全?
Is it safe?
而且 以防违背安全规则
And in case of any violationof a safety rule,
我们要达到安全状态
then we go to a’safe state’.
当然 在这方面 也有一些细节
There are, of course, some catches.
线装感应电动机昂贵而且很重
Linear induction motors areexpensive and heavy.
每一个驾驶室都需要有各自的一套装置
Each one of the cabsneeds to have its own set.
而且 这个电梯轴 从上到下
And the whole elevator shaft,from top to bottom,
需要用电磁线圈单元链接起来为它提供动力
needs to be lined with the magnetic coil units that power them.
为了减轻重量 这些驾驶室由碳纤维和铝制作而成
To save weight, these cabs are made of carbon fibre and aluminium.
因此 在现实中能否实现这一装置?
So will it work out in the real world?
蒂森克虏伯的这一模型告诉我们可以 但是
Thyssenkrupp’s models say it will, but
在这里已经被测试和批准过的产品
everything’s been tested and approved here,
下一步就是出售
the next step is to sell it.
对于这类建造摩天大楼的跨国公司
To the kind of enormous multinational companieswho build skyscrapers
和不喜欢冒险的人来说
and who do not like risk.
这可能是一种比把电梯安装在原来的位置
And that might be a greater challenge than making the elevators
更大的挑战
in the first place.
感谢蒂森克虏伯的每一个
Thank you very much to all the team
邀请我到这里的小组
at Thyssenkrupp who’ve invited me over here.
